PHP ODBC - How To Update Existing Rows in a Table?
Updating existing rows in a table requires to run the UPDATE statement with
a WHERE clause to identify the row.
The following sample script updates one row with two new values:
<?php
$con = odbc_connect('FYI_SQL_SERVER','sa','FYIcenter');
$sql = "UPDATE fyi_links SET notes='Nice site.', counts=8"
. " WHERE id = 102";
$res = odbc_exec($con, $sql);
if (!$res) {
print("SQL statement failed with error:\n");
print(odbc_error($con).": ".odbc_errormsg($con)."\n");
} else {
$number_of_rows = odbc_num_rows($res);
print("$number_of_rows rows updated.\n");
}
odbc_close($con);
?>
If you run this script, you will get something like this:
1 rows updated.
